What are the differences between a weighted keyboard and an unweighted keyboard, and how do these differences affect the playing experience?

A weighted keyboard has keys that are designed to feel like those of an acoustic piano, with resistance when pressed. This makes it more realistic and suitable for practicing dynamics and technique. An unweighted keyboard, on the other hand, has lighter keys without resistance, making it easier to play quickly but lacking the authentic feel of a piano. The differences in weight and feel affect the playing experience by influencing the player's touch sensitivity, control, and overall expression while playing.
